I recently shut down two small firms that I've run for years and years - the opportunity cost of not doing contract work or something else that paid decently was too much to keep at it.

...but I loved the code base, as clunky as it was. It had warts, scars, and stretch marks that documented its path through the years. I don't miss running the firms, but I do miss the code.

I'll be buying posters to hang on the wall and remind me of the good times.
